Fig. (5) No outlier removal procedures have been applied to the data so all participants are included in this graph. PRF center sizes averaged across participants in each group, plotted against eccentricity in V1. Red: Deaf participants, Black: Control group. Error bars denote +/- standard error of the mean. This demonstrates that the pattern of results is qualitatively the same prior to the stringent data exclusion procedures which were applied, suggesting these did not have a distorting effect on results.
